I run a modded cascade shift star and the shift pro shift kit with easy spring from tudors. :thumbsup:
I say go for it. Anyway you go will be fine and better then stock.
But just a FYI, you don't need the cases apart to do any of the three above mods. Just pop the clutch cover off and pull the basket and its all right there. But if it's apart already, your kickin goals.
